>> ..like "Ultrafire" - not exactly a sensible barndname for lithium=20 >> cells..... > > Like SureFire? I recently asked Russell about Li-ion cells to replace dead cordless tool NiCd After a couple of hours I'd come across both Ultrafire and SureFire, and many others too. Every single one had some caveat, a report of bad construction, poor performance, over-specced, fake, etc So I concluded I can't trust any Li-ion except the quite expensive from 'trusted' suppliers. And even then I'd have to test them to be quite sure I've not been ripped off Decided I will use a 12V SLA and inverter. Inconvenient in one way, probably needing to have the battery in a "fanny pack" or on a belt, but at least the tool itself will be lighter Joe=20 --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
